Humidity refers to the amount of water vapor present in the air. It plays a significant role in our daily weather and can affect how we feel. For example, on a hot day, high humidity can make the temperature feel even warmer because the moisture in the air makes it harder for sweat to evaporate from our skin. There are two main types of humidity: absolute humidity and relative humidity. Absolute humidity measures the actual amount of water vapor in the air, while relative humidity compares the current amount of moisture to the maximum amount the air can hold at a specific temperature. Understanding humidity helps us prepare for different weather conditions.
